This invention relates to new and useful improvements in a carbon blackrecovery device.

It is an object of this invention to provide a device for producingcarbon black having novel means for producing and recovering carbonblack.

In the petroleum industry, there are many instances where gas is wastedor, although discovered, can not be profitably produced for such reasonsas lack of pipe line facilities to a market. In such instances the gasis of no value and must be either ared or left in the formation. lt isan object of this invention to provide a means for converting the gasinto carbon black in the held adjacent the producing well or wells.

It is another object of the invention to provide a carbon blackproducing and recovery device having novel means for providing multipleburners and supplying said burners with an adequate amount of gas aswell as air for efficient combustion.

It is another object of the invention to provide a carbon blackproducing and recovery device having novel means for removing the carbonblack from rotating depositories.

It is another object of the invention to provide a carbon blackproduction and recovery device having novel burners providing easy andeiiicient means of controlling the ratio of air-gas feed to the burners.

It is another object of the invention to provide a carbon blackproduction and recovery device that may be portable and quicklyinstalled singly or in multiples, and that may be completely housed withnovel means for controlling the flow of air into the housing when inproduction.

With the above and other objects in view, the invention has relation tocertain novel features of construction, operation and arrangement ofparts more particularly defined in the following specifications andillustrated in the accompanying drawings, wherein:

FIGURE l1 is a side elevational view of a multiple recovery structure.

Referring now more particularly to the drawings, the numeral 1designates a lower section of tubular material on which a series oflower plates 2, 2 are mounted. Vertical tubular supports 3, 3 aremounted on and are in tubular connection with the lower section I and anupper section of tubular material d is mounted on and tubularlyconnected with the vertical supports'3, 3, forming a half circle frameA. A similar frame B is formed, and-the frameworks joined to form acircular structure. A center post 5 is mounted on the bottom plates 2, 2of the joined frames and a series of conduits 6, 6 are tubularly`connected to the vertical supports 3, 3 in each frameand eX- tendradially from and are tubularly connected with the inner verticaltubular members 7, which are spaced around the center post supportingplates 8, 8. The tubular members 1, 3, 4, 6 and 7 form a conduit systemin each frame into which a ilow of gas may be directed. The circularunit thus formed in two independent parts, A and B, receive a flow ofgas into their respective conduit systems through the common inlet 9when the parts are joined.

Mounted on the member 6 in each frame and tubularly connected therewithare the annular supply conduits 10, 10, which are concentric with thecenter post 5 when the parts are joined and on which the burners 1l, 11are mounted. Suitable burner tips 64 are seated in the upper ends of theburners 11.

Mounted on the center post 5 is an externally threaded sleeve 12 onwhich the annular center post sleeve support 13 is adjustably mounted.The center post sleeve 14 is rotatably mounted on the center post 5 anda pair of bushings as 15, 15 maintain the center post sleeve 14 invertical alignment with the post 5 and suitable ball bearings 16 mountedbetween the support 13 and sleeve 14 permit easy rotation of the sleeve14.

The sleeve -14 is outwardly flanged at its lower end and supports oneend of the plates 17, 17 upon which the carbon black is collected andwhich are triangular in shape and iit closely together to form thecircular collection plate when the parts A and B are joined. An angleiron rim 118 'forms a support for the other ends of the collectionplates 17, 17, and is suspended from the center post sleeve by means ofcables, as 19, which are mounted at one end to the cable eyes 2t) on therim 18 and to cable eyes as 21 on the center post sleeve 14. Thesecables may be provided with turn buckles (not shown) 'for adjustment,and are spaced around the center post sleeve at intervals to provide abalanced load. Mounted on the upper end of the rim 18 at spacedlintervals are the guide roller supports 22 on which the verticallyadjustable guide rollers 23 are rotatably mounted. An anchored guiderail 24 is .secured to the vertical members 3, 3 and provides a trackfor the rollers 23. The outer side wall of the rim 18 is grooved as at25 to provide a seat for the rotating cable 26.

The `entire unit, when joined, is inclosed by means of the bottom plates2 on each frame, the side plates 27 around the outer side wall of eachframe and the top plates 28 on each frame, so that when the frames A andB are joined, the inclosure is complete. Mounted on the top plates 28 isa .suitable air motor 30 and gear box 31, on one of the frames, and adrive shaft 32 extends downwardly through the top plates 28 from thegear box 3G) and a vertically adjustable pulley 33 is mounted on theshaft 32 on -which the rotating cable 26 is wound to im-l part rotationfrom the dniveshaft 32 to the rim 18.

Mounted beneath the collecting plates 17 and supported by the legs 34,34 in one of the frames is the auger housing 35 in Iwhich the rotatableauger 36 is mounted. The housing 35 extends outwardly through the sideplates 27 and upwardly to a suitable collecting tank 3S and a suitableing 35 extends outwardly through the side plates 27 and upwardly to asuitable collecting tank 38 and a suitable swivel joint 39 in the auger36 provides means for continuing the movement of collected carbon blackfrom the housing 35 to the tank 38. The housing 35 is enlarged over thearea directly beneath the plates 17 and the upper end of the enlargedportion is open. A pair of scraper plate shafts 40, d@ are ,mounted inthe open end of the housing 35 and a series of pivotal scraper platearms 41, 41 are mounted on the shafts 40, 4t). On the upper end of thearms 41 are the longitudinal scraper blades 42 which bear against theunderside of the collecting plates 17. The lower ends of the arms 41 areinwardly inclined forming ,crank arms and are provided with .suitableweights 43, 43 to provide the desired contact of the scraper blades withthe collecting plates.

Spaced at idesired intervals in the bottom plates 2 of each frame aresuitable air inlet dampers 44 which are slidably mounted in the tracks45, 4S and ywhich have the outwardly extending handles d'7,v 47. Ports46 in the plates 2 permit air to iiow into the area beneath the plates'17 and the dampers 44, 44 may be manually adjusted to control this liowof air.

The top plates 28 of each frame are inclined upwardly and inwardly andterminate against the common vent 47. A damper 48 is mounted in the vent47 and a manually adjustable control is provided by the projectinghandle 49.

On the lower end of the `drive shaft 32 is a suitable gear 50 which isin mesh with the gear 51 on the auger 36. The drive shaft 32 extendsthrough a suitable bearing 53 adjacent the housing 35.

Each burner 11 is provided with an inclosure 54 having ports 55 in thebottom thereof for the ow of air'to the burner. Another form of burneris shown in FIG- URES 8, 9 and 110, where the annular conduits 57 havethe burners 58 mounted thereon and tubular connection is establishedtherewith, and which extend upwardly through a perforated support suchas a Ilayer of expanded metal 59. An inclosure I60* is seated on theexpanded metal 59 and is provided with a series of yvertical elongatedports I61, 61. An annular shield 62 is mounted on the expanded metal 59around the inclosure 60 and is provided with elongated slots 63. Theinclosure 60 may be rotated to bring the ports 6.1 into alignment withthe slots l63', or such alignment as is desired, to control the flow ofair to the burner S8.

`In operation, the device may be conveniently transported to the placeof operation by ldisassembly into the two half circular frames A and B,the top plates 2.8, the center post assembly consisting of the Icenterpost 5, bushings 15 and sleeve 14, and the support 13, and theventillator 47. When the location of operation is reached, the device isreassembled and the gas supply fed into the inlet 9 and the burnersignited. The distance of the collection plates 17 from the top of theburners 11 is set by rotation of the support 13 which will elevate orlower the sleeve 4 and the plates 17. The plates 17 are leveled by meansof the cables 19 after the support 13 has been set. The amount of air tobe admitted into the area beneath the burners is determined by adjustingthe dampers 44 in the lower plates 2 and the motor 3) is started,rotating the shaft 32, which in turn rotates the rim y18 through thecable 26, and rotating the auger 36 through the gears 50, 51. As the gasburns, carbon black will be deposited on the bottom of the plates 17 andas the plates 17 pass over the Scrapers 42, the carbon black will bescraped orf of the plates 17 and will drop into the housing 3S where itwill be carried by the auger 36 into the depository 38. The scrapers 42are preferably in two rows, with the rearmost row overlapping theforwardmost row so that the entire plate area will be scraped.

If the volume of gas to be burned is greater than the capacity of asingle device, the device may =be duplicated land stacked as illustratedin FIGURE ll, the lowermost unit 64 being identical to that abovedescribed with the omssion of the top plates 2S and the upper unit 65being mounted on the lower unit, the drive shaft 32 shown in FIGURE 4being extended to accommodate Iboth units and the vent 66 providingventilation for both units. In

arcanes such arrangement, only the lowermost unit would be provided withlo'wer plates -and the damper control for both units would be controlledin theV lower unit. An independent feed inlet .as 67 and 68 would -beprovided for each unit and an independent conveyor assembly 69 and 7)-being provided for each unit, the motor 71 Iand gear box 72 beingcommon to lboth units.

Vthile the foregoing are considered preferred forms of the invention,they Iare by way of illustration only, the

broad principle of the invention -being dened by the appended claims.
